Application filed November 28, 1916.. Serial Ito. 133,843.

To all whom it may concern:

Be it known that I, IMoenN N. THOMAS, a citizen of the United States, residing at Troy, in the county of Rensselaer and State of New York, have invented a new and use-' ful Improvement in Charging-Fittings for Beverage-Carbonators, of which the followin is a specification.

his invention relates to a fitting which is designed to be applied to a fountain or similar beverage container and be connected with piping from a source of carbon dioxid under pressure; with piping from a supply of pure or mineral water which is to be charged with the gas and retained inithe fountain under pressure until dispensed or drawn for further use; and with piping to the draft outlet or draw ofi.

The object of the invention is to provide a simple, cheap and compact fitting that may be readily. applied to or removed from a fountain or similar container for charged liquid, which is so constructed that the several necessary pipe connections and required safety and escape valves can be easily and quickly attached in such manner that the joints will be tight, and the liquid and gas commingled very efficiently and economically.

Of the accompanying drawings Figure 1 'is a central vertical section of the fitting showing it attached to the head of a fountain. Fig. 2 shows a plan of the fitting. Fig. 3 shows a side view of the fitting, without the water sprayer and the outflow tube. Fig. 4 is a horizontal section taken on the plane indicated by the dotted line 4-4 on Fig. 5.. Fig. 5 is a horizontal section of the fitting on the plane denoted by the dotted line 5-5 on Fig. l.

The fitting illustrated has a cyhndrical body 1. Extending downward from the lower side of the body is a stem 2 that is threaded so that it may be readily screwed into the mouth in thetop 3 of a fountain, and eztendin upward from the upper side of the body is a-hub d that is of angular outline for the convenient application of the wrench which may be used to screw the stem into or unscrew it from the rhouth of the fountain.

In the center of the body of the fitting and opening downward through the stem-1s a chamber 5, and ending from the periphery radially inward to this chamber is a pemage 6. The walls of the outer end or? I Specification of Letters Patent.

this passage are threaded forthe convenient opening 9' that is threaded for the convenlent connection of the end of the pipinfig which leads to the draft faucet or draw A. perforated conical shell or sprayer 10 is secured to the bottom of the stem over the lower end of the chamber 5 and about the outflow tube 7.

Opening part way into the body from one side is a passage 11. The walls of the outer end of this passage are threaded forthe connection of the piping from the supply of gas. From the inner end of this passage down through the-body is a hole 12, and in line with this hole the threads on the exterior of the stem are cut away so as to form a groove 13 in the outer wall of the stem.

- Opening part way into the body from an-' other side is a passage 14, the walls of which at the outer end are threaded for the connection of the stem of a safety valve that may he provided to relieve any excess pressure in the .tountain. "A hole 15 is made from the inner end of this passage down through the bottom of the body, and in line with this hole the threads on the stem are.

cut away so as to form a groove 16. At an.- other point a radial passage 17 may be made from the periphery part way into the body, and the outer end of this opening maybe threaded for the connection of the stem of a blow ofi cock. A hole 18 is made from the inner end of this passage down through the body, and the threads of the stem in line with this hole are cut away to form a groove 19. A gasket or lead washer 20 is fitted upon the base of the stem to insure against leakage when the fitting is screwed into the mouth of a fountain.

When the fitting is screwed into the mouth of the fountain ready for use the water supand at the desired time water is allowed to enter through this passage to the chamber 5 and flow down through the sprayer 10 and out into the fountain. The gas supplr pipe is connected with the passe 11 Mid . ply pipe is connected with the passage 6 9 and when charged fluid is drawn out it flows up from the bottom or the fountain through the tube 7 to the passage 9. lit a safety valve is connected with the passage 1d the gas pressure is exerted upward through the groove 16 cut across the threads of the stern so as to actuate the safety valve, and it a relief valve is connected with the passage 17, when it is opened the fluid that it is desired to allow to flow vout passes upward through the groove 19 cut across the threads of the stern,

This fitting is an integral casting and the chamber and passages are easily formed particularly the grooves that are out across the threads of the stem, thus making it very cheap to manufacture. it can he readily atv tachcd to or removed from a fountain and can he easily and quickly connected with the gas, water and draft piping and pro vided with safety and relief valves if desired. The connections can all be made so as to eliminate the possihility oi leaking and the .gas and liquid are coingled in a very ethcient manner,
